The property editor has undergone a major redesign. This guide will help you understand what’s changed, why we made these updates, and how to get up to speed quickly.

What changed

Reorganized for clarity: Properties are grouped into logical tabs (Visual, Interaction, Conditional) with collapsible sections. You can drag-and-drop to reorder conditionals, constraints, workflow fields, custom states, and more. And you can now see the count of workflows, conditionals, and custom states on each element, so there's less scrolling, less tab-switching, and more visibility into how your elements are set up.
New tools shaped by community feedback: Global expressions, workflow editing, agent entry points, searchable color picker, expandable dynamic expressions, and more.
Built on a modern foundation: We've migrated to SolidJS and a new design system, which means faster bug fixes, quicker feature releases, and the groundwork for efficient AI capabilities in the editor.

Recent updates we’re excited about

Only available in the new property editor.

Dark mode editor

A long-requested update. Toggle it on from the moon icon at the bottom left of your editor sidebar.

Global saved expressions

Another highly requested update that lets you define an expression once and reuse it across your app.

Add and edit workflow events and actions

What’s changed

Light mode / Pinned PE

Before	After
Displayed in dark mode only	Updated to light mode
Positioned as a floating interface element	Integrated as a pinned element within the layout
Visually separated from the primary layout	More clearly anchored within the page structure
Less predictable placement during scrolling	Provides a consistent and predictable location
Difficult for our engineers to improve	Creates room for future updates to the canvas

Same tabs, New names

Before	After
Appearance, Layout, and Conditional	Visual, Interaction, and Conditional
Emphasized styling and page structure	Emphasizes user intent and behavior
Reflected a more implementation-focused mindset	Reflects a more design-forward mental model

Re-organized and collapsible sections

Before	After
Properties were presented in long, static lists	Properties are grouped by purpose
Related settings were spread across multiple areas	Logical sectioning reflects how builders use each element
Sections could not be collapsed	Sections can be collapsed to reduce visual noise
Visual scanning required frequent scrolling	Frequently edited settings are surfaced earlier with new intuitive icons

More control of your editor

Resize as you need it

Show/hide your editor as you build

Unpin your elements tree when you want

Size and layout properties have a new home

Before	After
Sizing and layout settings were fragmented	All size and layout attributes are consolidated into one tab
Width and height controls lived alongside unrelated fields	Layout controls live together in one section
Responsive configuration required context-switching	Responsive behaviors can be adjusted in one pass

Building responsively made easier

Before	After
Responsive behavior had to be configured manually	Padding and margin behavior is standardized
Layout tuning required additional setup	Fixed, fill, and fit dropdown replaces legacy checkboxes
Standard properties for configuring alignment	Modern, visual nine-grid view of element’s alignment
Manually add in spacing for all sides	Easily add or edit spacing options for vertical or horizontal

Drag-and-drop conditionals

Before	After
Most properties were visible at once with little organizational structure	Additional properties are now revealed through a plus (+) control, making it easier at a glance
Reordering required multiple clicks	Drag and drop re-ordering is properly supported
Conditional properties can get lengthy and take up space	Conditionals can be collapsed by clicking in the header row for more breathing room
Creating a new conditional adds it to the bottom of the tab, potentially out of view	Conditionals scroll into view upon creation

Conditional names

Before	After
Conditionals displayed the full expression as the label	Conditional names are customizable
Identifying logic required reading the entire rule	Logic can be understood without expanding each rule

View connected workflows events and actions

Before	After
Adding workflows to elements while designing required switching to a new editor tab	Frontend workflows are visible in-context
No ability to see the events and actions from the Property Editor	New ability to edit existing actions and create new events from the Property Editor *Note: Planning to build out additional functionality during the beta

Edit fields and operators in expressions without deleting them

Before	After
Editing fields or operators meant deleting the entire constraint and rebuilding it from scratch which was slow, disruptive, and easy to mess up.	Edit fields and operators directly in place. No more deleting and rebuilding constraints. Make quick tweaks without breaking your flow, so iterating on logic is faster and less error-prone.

Edit workflow actions directly in the property editor

New custom states panel

Before	After
Custom states were hidden behind an info icon	Custom states have a dedicated panel
Discoverability depended on prior knowledge	Access requires no navigation
Required to click into action in order to see if custom states have been added	See if there are custom states added on an element right away

New color picker

Before	After
Colors were entered manually or selected from small lists	Full variable list appears in one view
Variable discovery was limited	Searchable variable lookup
Searching required manually scrolling through	Live previews update immediately
Navigating to the styles tab to edit a color variable	Directly edit while you’re mid-building
